Most hi end scopes have no yardage markers for parallax , I own many Tier one optics , their are a few exceptions but most have no numbers , they are not a range finder , but the March is a great scope where as most in same like vortex3 1-10 , PM2 1-8 ,or even ATACR 1-8 have fixed parallax ,. but with most AR type scopes on low power or using as a 3 gun the 1x is for a red dot and low power doesn't really have much use for parallax ,
I like the LPVO or low power variable optics for hunting @ short to mid ranges when you want a light set up , cause I know with me shedding 1.5 pounds over one of my hi power scope , makes a big difference after carrying in the woods all day . so they both have different uses , I wouldn't use my 1-8 or 1-10 powers for ultra long range banging steel plates . or shooting at tiny targets at long ranges , the main thing is scopes have repeatability when cranking turrets and keeping poi with temp changes and banging around ,
